BACKGROUND

The assembling of connectors both on land and underwater is a necessaryfunction during marine vessel operations. When handing cables forexample, it is imperative to avoid abrasion, crushing, twisting orkinking. It is known to use strap wrenches to assemble cable connectors.However, this known method of assembly, although effective, alsopresents difficulties because the strap wrench method may sometimes bedifficult to operate. If used improperly, the strap wrenches applyopposing torsion forces on the connector moldings cause the connectorpins to bend, which damages the connector and allows the connector toleak. In cables for example, kinks and bends cause increased voltagestanding wave ratio and signal loss during system operation. It isdesired to have a tool for assembling connectors without the undesiredeffect of producing torsion forces that damages connector moldings.

DETAILED DESCRIPTION

FIG. 1A is an isometric view of a tool 100 for eliminating torsion andfor holding opposing cable heads during cable servicing operations,according to an embodiment of the invention. Cable servicing operationsmay include the connection and/or the disconnection of male and femalecable heads. FIG. 1B is an exploded view of the tool 100. The tool 100may be made from any desired material. According to an embodiment of theinvention, the tool is made from alloys such as aluminum and steel.

As shown in FIGS. 1A and 1B, the tool 100 includes a handle portion 110.The handle portion is made up of a first substantially L-shaped link 120and a second substantially L-shaped link 140. As outlined below, theuser manipulates the handle portion 110 of the tool 100 to operate thetool. FIG. 1B shows each substantially L-shaped link having a controlarm that a user holds, and a working arm that is attached to arespective clamping portion. As shown, the first substantially L-shapedlink 120 has control arm 122 and working arm 124, the two arms meetingat an apex or elbow region 123. As shown, the control arm 122 issubstantially 1-shaped, and the working arm 124 has a substantiallytriangular shape.

Similarly, the second substantially L-shaped link 140 has a control arm142 and a working arm 144, the two arms also meeting at an apex or elbowregion 143. Similar to link 120, as shown, the control arm 142 issubstantially I-shaped, and the working arm 144 has a substantiallytriangular shape. As shown in FIG. 1A, the control arms 122 and 142 eachhave a length L, and the working arms 124 and 144 have a length l.According to an embodiment of the invention the length L is about 9 into about 15 in, and the length l is about 4 in to about 8. In onespecific embodiment the L is about 12 in and the length l is about 6inches. The handle portion 110 is dimensioned so that an operator mayuse a single hand to operate the control arms (122, 142), leaving theuser's other hand free to perform servicing functions.

As shown, the tool 100 also includes first and second clamping members200, which are substantially identical. The first clamping member 200 isattached to the working arm 122 of the first substantially L-shaped link120. The second clamping member 200 is attached to the working arm 144of the second substantially L-shaped link 140. As outlined below, whenattaching cable connectors, the first and second clamping members 200are used to provide a compressive force, without adding undue torsion onthe respective connection moldings.

The exploded illustration of FIG. 1B shows the working relation amongthe different elements of the tool 100. As shown, the firstsubstantially L-shaped link 120 is actually formed from two flat platelike members 120 a and 120 b, which are separated by stopping plates 121and 125, thereby forming a hollow member with an opening 129. Thestopping plate 121 may be a flat rectangular plate, and the stoppingplate 125 may be a triangular plate that corresponds to the shape of theworking arm 124. FIG. 1B also shows the second substantially L-shapedlink 140 being a flat plate. The dimensions of the substantiallyL-shaped links 120 and 140 are such that the flat second substantiallyL-shaped link 140 fits within the opening 131 of the first substantiallyL-shaped link 120. As shown, the opening 131 has a width w and thesecond substantially L-shaped link 140 has a thickness t which allowsthe link 140 to fit within the opening 131. According to an embodimentof the invention, w is about 0.75 in and t is about 0.5 in.

FIG. 1B also shows the links 120 and 140 pivotally attached to eachother. A pin 130 extends through pivot openings 129 of the first link120 and 149 of the second link 140, to enable a pivoting motion betweenthe substantially L-shaped links 120 and 140. FIG. 2B also illustrateswashers 132 and knot 135 that properly secure the attachment between thelinks 120 and 140. It should be noted that other known attachmentdevices may be used to provide a pivoting arrangement between the links120 and 140.

FIG. 1B also shows the different elements of the first and secondclamping members 200, which are substantially identical. Thus, thedescription of the first clamping member 200, as outlined below, is thesame as the description of the second clamping member 200, with likeelements identified with the same reference numerals. As shown, thefirst clamping member 200 includes a support track 220, a gripperholding member 240, and a gripper 260. As shown, the support track 220is attached to the working arm 124 of the link 120. The support track220 is fixedly attached to the link 120 by pins 222 that extend throughpin holes 225 in the gripper support track 220 and corresponding holes127 in the stopping plate 125. The support track 220 also includes aplurality of spaced apart adjustment holes 230, which as outlined belowprovides adjustability between the support track 220 and the gripperholding member 240. These holes 230 may be equally spaced apart, and maybe located in the underside of the support track 220, and may onlypenetrate to about midway through the body of the support track 220.According to this embodiment, the holes 230 are only visible from thebottom of the support track 220. FIG. 1C, a side view of the supporttrack 220, shows the spaced apart adjustment holes 230, which extend toa midway region of the body of the support track 220. As outlined above,the adjustment holes 230 may be equally spaced apart. FIG. 1C alsoillustrates pin holes 225 that extend from a bottom portion to a topportion of the support track 220.

The gripper holding member 240 includes a track opening 242 throughwhich the support track 220 slidably extends. The gripper holding member240 also includes overhanging edges 245 that allows the gripper holdingmember to cling to the support track 220, thereby providing additionalsupport between the support track 220 and the gripper holding member240. The gripper holding member 240 also includes a spring loaded pinarrangement that includes a pin 250, a spring 252, a bracket 254 havingan elongated opening 256, a lever 255, screws 257, and end cap 258. Thepin 250 is positioned within the body of the gripper holding member 240,so that it protrudes out of the body through a pop-up hole 251. Thespring 252 biases the pin 250 to extend through the pop-up hole 251.Screws 257 are used to hold the bracket 254 against the body of theholding member 240. The lever 255 is attached to the bracket 254, theholding member 240, and the pin 250, by means of the end cap 258. Thelever 255 is slidable with respect to the bracket 254, the elongatedopening 256 allowing a sliding in the vertical direction. A user slidesthe lever 255 to control the vertical positioning of the spring loadedpin 250. Thus, in operation, a user pops the pin 250 into an out of thespaced apart adjustment holes 230, in order to lock the gripper holdingmember 240 and the attached gripper 260 at a specific position withrespect to the track 220. As outlined below, the position of the gripperholding member 240 and the attached gripper is selected based on thedimensions of the connector molding that is being serviced.

FIGS. 1A and 1B show the gripper 260 pivotally attached to the gripperholding member 240. As shown, the gripper 260 is positioned within asubstantially U-shaped gripper cavity 255 of the holding member 240,between extending gripper holding arms 259. As shown in the explodedview of FIG. 1B, hinge screws 262 extend through openings 264 and 266 tocomplete the pivoting arrangement, which allows the gripper to pivotwith respect to the holding member 240 within the gripper cavity 255. Asoutlined below, this pivoting motion allows the gripper to maintain acompression force parallel to a central axis of the connector molding ofthe cable that is being serviced. Additionally, it should be noted thatbecause of the use of two hinge screws 262 and the overall arrangementof gripper 260 with respect to the gripper holding member 240, pivotingis allowed about only one axis, an axis that extends through a commonlongitudinal axis of the hinge screws 262.

As shown, the gripper 260 has a front receiving surface 261 which is aplanar surface, and a rear receiving surface 263, which is also a planarsurface, and is substantially parallel to the front receiving surface261. The gripper 260 also includes an opening 270 extending from thefront receiving surface 261 to the rear receiving surface 263, throughwhich a connector is received. FIGS. 1A and 1B also show the opening 270having a continuous gripping surface that includes a flat portion 275and a conical portion 277. As shown, the flat portion 275 of thecontinuous gripping surface is in a plane that is substantiallyperpendicular to the planes of the front and rear receiving surfaces 261and 263. As shown, the diameter D of the conical portion 277 is largerat front receiving surface 261, as compared to the diameter d towardsthe rear receiving surface 263. As shown in FIG. 1A, the second clampingmember 200 is arranged to be mirror-like reflection of the firstclamping member 200. Thus, the front receiving surfaces 261 of each ofthe first and second grippers 260 are positioned so that they face eachother.

FIG. 2A is an exemplary bottom view of a gripper 260, showing theconical surface portion 277 and the conical slope β. FIG. 2B is anexemplary front view of a gripper 260, showing the conical surfaceportion 277. FIGS. 2A and 2B also show different dimensions of thegripper 260, including the diameter D of the conical portion at thefront of the receiving surface 261 and the diameter d towards the rearreceiving surface 263. FIG. 2A shows the gripper having a thicknessT_(g) and a length L_(g). FIG. 2B also shows the gripper length L_(g).FIG. 2A also shows a thickness t_(g) of an arc portion towards rearreceiving surfaces. FIG. 2B also shows the gripper width W_(g).According to an embedment of the invention, the diameter D is about 1.8in to about 2.1 in, the diameter d is about 1.2 in to about 1.3 in, thethickness T_(g) is about 0.7 in to about 0.8 in, the thickness t_(g) isabout 0.10 to about 0.15, the length L_(g) is about 3.8 in to about 4.1in, and the width W_(g) is about 2.9 in to about 3.1 in. Additionally,the conical slope β may be about 15 to about 45 degrees. FIG. 2C is anexemplary illustration of male and female connector moldings 301 and 302arranged for attachment to each other, the moldings 301 and 302 havingconical portions 307 and 308, respectively, commensurate with theconical portion 277 of the gripping surface of gripper 260. Thus theconnector moldings 301 and 302 may also have a conical slope of about β.As outlined below, the conical portion 277 of the gripper 260 grippermay be used to grip conical portions 307 and 308.

FIG. 3A is an exemplary illustration of a tool and connector arrangement222, prior to servicing the connector arrangement, according to anembodiment of the invention. As shown, the arrangement 222 includes atool 100 and male and female connector moldings 301 and 302, which arecable head portions of cables that are being serviced. In the instantarrangement, the male and female connector moldings 301 and 302 are tobe connected. FIG. 3A also shows a surface 201 upon which the tool 100and/or the connector moldings 301 and 302 may rest. Because the instantinvention is directed towards both land and underwater environments, thesurface 201 may be a land or an underwater surface. FIG. 3A shows thetool 100 with the first and second control arms 122 and 142 of therespective substantially L-shaped links 120 and 140, in a pivoted-apartorientation. FIG. 3A also shows each clamping member 200 securing aconnector molding (301, 302) within the respective gripper 260. Asoutlined above, each connector molding may include a conical portion(307, 308), which is gripped by a matching conical portion 277 of thegripping surface of the respective gripper 260.

FIG. 3A further illustrates variable angle α formed between the gripper260 and the gripper holding member 240. As shown, the male and femaleconnector moldings 301 and 302 are maintained in a direction that issubstantially parallel to the surface 201, which prevents theapplication of undesired torsion on the connector moldings 301 and 302.

In operation, a user applies squeezing forces F₁ and F₂, as shown, tothe control arms 122 and 142 of the substantially L-shaped links 120 and140. Because of the dimensions and design of the L-shaped links 120 and140, a user may use only one hand to apply the squeezing forces F₁ andF₂. The application of the squeezing forces F₁ and F₂ creates resultingpushing forces P₁ and P₂, pushing the cable connection heads together.As shown, the pushing forces P₁ and P₂ are directed substantiallythrough and parallel with a central longitudinal axis X that is commonto both male and female connector moldings 301 and 302. The ability ofthe gripper 260 to pivot at variable angle α with respect to the gripperholding member 240 allows the tool 100 to apply the pushing forces P₁and P₂ along the central longitudinal axis X. The application of thepushing forces P₁ and P₂ in the illustrated direction, which is alsosubstantially parallel to the surface 201, prevents the application ofundesired torsion on the connector moldings 301 and 302.

FIG. 3B is an exemplary illustration of a tool and connector arrangement224, after the user applies squeezing forces F₁ and F₂ and moves theconnector arrangement into a servicing position, according to anembodiment of the invention. Thus, FIG. 3B illustrates the tool andconnector arrangement in a servicing orientation. As shown, holdingforces F₃ and F₄ may be continuously applied to maintain the male andfemale connection moldings 301 and 302 in illustrated orientation. FIG.3B shows the male and female connection moldings 301 and 302 contactingeach other, with compression forces C₁ and C₂ exerted on the connectionmoldings 301 and 302. The compression forces C₁ and C₂, which compressthe connection moldings 301 and 302 together, result from the appliedholding forces F₃ and F₄. As shown, the compression forces C₁ and C₂ aredirected substantially through and parallel with the centrallongitudinal axis X that is common to both male and female connectormoldings 301 and 302. As stated above, the ability of the gripper 260 topivot at variable angle α with respect to the gripper holding member 240allows the tool 100 to apply the compression forces C₁ and C₂substantially along the central longitudinal axis X. In the illustrationof FIG. 3B, the angle α is about 180 degrees.

During servicing operations, when the tool and connector arrangement isas illustrated in FIG. 3B, a user may use one hand to apply the holdingforces F₃ and F₄ and the user may use the other hand to rotate acoupling ring 306 of the female connector 302 over the receiving portion305 of the male connector 301. The coupling ring 306 and the receivingportion are provided with complementary threading arrangements. Becauseof the resulting compression forces C₁ and C₂ substantially parallel toa common longitudinal axes X, the user is able to rotate the couplingring 306 over the receiving portion 305 so that the thread is under noload. This ensures free rotation of the ring 306 with no binding. Thus,the user continues rotating the ring 306 until the connectors are fullyseated. It should be noted that the forces F₁, F₂, F₃, F₄, P₂, C₁ andC₂, as outlined above, may be any desired force necessary to provideproper squeezing, holding, pushing, and compression.

FIG. 4 is a flowchart illustrating a method 400 of securely attachingfirst and second cable heads according to an embodiment of theinvention. The steps involved in the method 400 of securely attachingfirst and second cable heads have been outlined above in detail in thedescription of FIGS. 1A-3C. FIG. 4 merely shows the general stepsinvolved, but is not an all-inclusive illustration of the method 400.

Step 410 is the providing a first cable head having a first connectormolding 301 with a male thread arrangement 305. Step 420 is theproviding a second cable head having a second connector molding 302 witha female thread arrangement 306. Step 430 is the arranging of the firstand second cable heads opposed to each other for the attachment of themale thread arrangement 305 of the first connector molding 301 to thefemale thread arrangement 306 of the second connector molding 302. Theconnector moldings 301 and 302 are arranged along a surface 201 as shownin FIG. 3A. The surface 201 may be a land or an underwater surface. Thefirst and second cable heads, as illustrated in FIG. 3A, are spacedapart and opposed to each other in a manner outlined in step 430.

Step 440 is the providing a tool 100 for eliminating torsion and forholding the opposed cable heads during the secure attachment anddetachment of the cables. As shown in FIGS. 1A and 1B, the tool 100includes a handle arrangement 110 having pivotally attached first andsecond substantially L-shaped links 120 and 140, the handle arrangement110 operable by only one hand of a user. The tool 100 also includesfirst and second clamping members 200, wherein the first clamping memberis fixedly attached to the first substantially L-shaped link 120 and thesecond clamping portion 200 is fixedly attached to the secondsubstantially L-shaped link 140. As illustrated in FIGS. 1A and 1B, andas outlined above, each clamping member includes an opening 270 and agripping surface (275, 277).

Step 450 is the securing of the first and second connector moldings 301and 302 to the first and second clamping members 200, respectively, byreceiving the cable connector moldings (301, 302) through the opening270 and gripping the connector moldings (301, 302) with the respectivegripping surfaces, as shown in FIG. 3A.

Step 460 is the squeezing and holding together of the pivotally attachedfirst and second substantially L-shaped links 120 and 140 of the handlearrangement 110 thereby moving the first and second clamping members 200together. As outlined above, this squeezing and holding may be performedwith only one hand of a user. This movement pulls the respectiveconnector moldings 301 and 302 together, from the orientation shown inFIG. 3A to the position shown in FIG. 3B. When the first and secondconnector moldings 301 and 302 are pulled together and the first andsecond substantially L-shaped links 120 and 140 are held together asshown in FIG. 3B, compression forces are applied to the connectormoldings 301 and 302. As outlined above, because of the structure of thetool 100, the compression forces are substantially parallel to a commoncentral axis X of the connector moldings.

Step 470 is the rotating of the female thread arrangement 306 of thesecond cable head in a first direction over the male thread arrangement305 of the first cable head connecting to properly attach the first andsecond cables. As stated above, according to an embodiment of theinvention, the holding of the handle portion 110 and the rotating of thefemale thread arrangement 306 over the male thread arrangement 305 maybeperformed simultaneously by a single user. Additionally, the user mayuse one hand to hold the handle arrangement and the other hand to rotatethe cover 305. As stated above, because of the resulting compressionforces C₁ and C₂ substantially parallel to a common longitudinal axes X,the user is able to rotate the coupling ring 306 over the receivingportion 305 so that the thread is under no load. This ensures freerotation of the ring 306 with no binding.

It should be noted that alternatively, the tool 100 may be used todetach already attached connectors. According to this embodiment, themale and female connection moldings 301 and 302 would be held againstthe surface 201 by the tool 100 in the orientation as shown in FIG. 3B.Holding forces F₃ and F₄, as shown in FIG. 3B, are applied to the handleportion 110, which creates the compression forces C₁ and C₂ on the cableheads in a direction substantially parallel to the common axis X. Thiseliminates torsion forces so the thread is never under load, therebyensuring free rotation of the ring with no binding. This makes it easierfor the user to disconnect the connector moldings 305 and 306 from eachother. As outlined above, a single user may use one hand to hold thehandle arrangement and the other hand to rotate the coupling ring 306for disconnection.
